SPECIFICATION forming part of Letters Patent No. 293,645, dated February19, 1884. Application filed May 18, 1883. (No model) .To all whom it mayconcern:

Be it known that 1, WILLIA H. FosrER, a citizen of the United States,residing at Jeffersonville, in the county of Clarke and State ofIndiana, have invented a certain new and useful ImprovementinClamp-Hands for Hold-' ing Files; and I do hereby declare thatthefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being hadto the accompanyingdrawings, forming part of this specification.

This my invention relates to certain new and useful improvements inclamp-handles for holding files, consisting, first, in a handle the tinepart of which constitutes one of the jaws, the end of which is turneddown to an angle with thehandle, and has a flange on the end, the faceof which is on a line with the handle, with a small rabbet on the insideedge and a flange on the outside to hold the file. This last-named j awis provided with another, made similar in form without the tine, securedto the side by means of thumb-screws, and by means of which the jaws areclosed upon the file. The object of thismy invention is to provide animproved handle for operating files that will be cheap, durable, andconvenient in use, and that may be so adjusted as to suit any size offiles, and may be attached to any required part of the file where thepressure is required without the use of the other hand to do more thangive it the proper direction. I attain the above objects by themechanism illustrated in the drawings, in which- Figure 1 is aperspective view of the de- Fig.

2 is aperspective view, showing the flanges" and rabbet or groove on theunder side.

. Similar letters refer to similar parts throughout the several views. 1

In the drawings, A represents the handle and tine of the device, whichis made similar to those now in use, and B is the stationary jaw formedon the end, which is about the same thickness of the tine and stands atan angle therewith, having the anglecorner rounded and the lower endwidened somewhat in the form of an inverted T, to give more bearing uponthe file, and is further provided with a flange, H, on the outside ofthe lower edge, formed as shown in the drawings.

0 is the loose or adjustable jaw, which is made in form to match the jawB,with corresponding rabbet, F, and flange H, and is secured to thejaw Bby means of thumb-screws D and E.- The lower screw, E, is intended forthe purpose of closing the jaws upon the file,

while the upper screw, D, is intended, by means of its leverage inconnection with the screw-power, to secure the file more firmly betweenthe jaws.

G G are recesses or notches in the flanges H, to take away weight andassist in clamping thefile more securely, which is done by inserting thefile between them at the required point, andthen close up the screw E,which clamps the file, which is further tightened by screwing up thescrew D, by means of which it is held firmly.

Having thus fully described my invention,

therefore, what I claim as my invention, and desire to secure by LettersPatent, in handles for clamping and holding files by meansof screw andleverage power combined, is

In clamp-handles for files, having tine A, with stationary jaw B, flangeH, and rabbet F, as above described, combined with the movable jaw 0,having flange H, rabbet F,and setscrew E, which is used for the purposeof closing the jaws upon the file, and also to answer as a fulcrum whenthe jaws are forced up more firmly by the screw D, substantially asdescribed, and for the purpose set forth.
